摘　　要：目的探讨心电图在诊断急性正后壁心肌梗死中的价值。方法选择我院心血管内科收治的56例心肌梗死患者为研究对象,所有患者均经病理学确诊,入院后均接受常规心电图检查和右胸导联分析。分析患者的心电图变化情况。结果心电图的诊断符合率为98.21%。急性正后壁心肌梗死患者V1、V2导联上R波逐渐增高增宽、从r S演变成为RS或Rs型,ST向量指向后壁、背离前壁,表面为V2、V3导联ST段降低≥0.2 m V。结论针对急性正后壁心肌梗死可行心电图监测,及时加做后壁导联,结合患者临床症状和心肌酶谱监测结果,以提高诊断准确率。Objective To investigate the value of electrocardiogram in the diagnosis of acute postive posterior wallmyocardial infarction. Methods A total of 56 cases of myocardial infarction admitted in our department of cardiology wereselected as study objects and diagnosed by pathology, all the patients received routine electrocardiogram and right chest leadanalysis. The changes of patient＇s electrocardiogram were analyzed. Results The diagnostic accordance rate of electrocardiogramwas 98.21%. In patients with acute postive posterior wall myocardial infarction, the upper R wave of V1 and V2 leads graduallyincreased and widened, evolution from rS to RS or RS, and the ST vector pointed to the posterior wall and deviates from theanterior wall, the surface was ST segment of V2 and V3 leads reduced ≥0.2 mV. Conclusion Electrocardiogram monitoringcan be performed for acute postive posterior wall myocardial infarction, posterior wall leads can be added in time, andcombine the clinical symptoms and myocardial enzyme spectrum monitoring results to improve the diagnostic accuracy.
